The Milwaukee County Medical Examiner's office said Friday that three infant death cases this month were results of co-sleeping.

Six-week-old Sesilia Sandoval, 6-week-old Yasmine Ashley and 11-week-old Demirrion Wilson had all been sleeping with their mothers before being found unresponsive.

None of the children had any signs of trauma.

The exact causes of death are still being determined.

The city of Milwaukee launched a campaign this fall to reduce the city's infant mortality rate by 10 percent. According to city health officials, co-sleeping leads the list of infant death causes.

According to the city, 10 babies out of every 100,000 born in Milwaukee die before their first birthday.

"Everyone in this state should be embarrassed by the fact that our largest city has infant mortality rates for African-American babies that are higher than Third World countries," Milwaukee Mayor Tom Barrett said.
